A 67-year-old woman was killed and three people were injured in a six-car collision on Lakeville Highway in Petaluma Tuesday morning, a Petaluma police lieutenant said.

A 19-year-old male driver in a Chevrolet Silverado was driving west on Lakeville Highway toward Petaluma around 7:15 a.m. when he crossed over solid, double-yellow lines into the eastbound lane and collided head-on with the woman’s Toyota Prius, Lt. Ron Klein said.
